BEAD FOIE JEVJELR'Z.

Application filed. July 24, 192,2. Serial No. 576,989.

T all @07mm it may concern:

Be it known that I, HENRY F. JUnnGnNs, a citizen of the United States,residing at Providence, in the county of Providence and State of Rhodelsland, have invented cer tain new and useful Improvements in Beads forJewelry, of which the following is a specification. y

My invention relates to ornamental beads l0 primarily designed forjewelry.

The essential objects of my invention are to simulate stones, gems, andornaments of an expensive character in an inexpensive material; todiminish weight; insure beauty; and to attain these ends in aninexpensive structure.

A further essential object is to construct beads in a simple, facile,and inexpensive manner.

To the above ends essentially my invention consists in such parts and insuch combinations of parts, and in such steps and in such successions'of steps as fall within the scope of the appended claims.

vln the accompanying drawings which form a part of this invention-Figure 1 is a side elevation of a bead embodying my invention showing anattaching wire therein.

Figure 2, a section of the same on line 2-2 of Figure 1,

Figure 3, a section on line 3- 3 of Figure Figure 4, a perspective viewof the partition disk,

Figure 5, a diametrical section of a modified form of my invention,

Figure 6, a perspective view of the disk shown in Figure 5,`and

Figure 7, a side elevation of a bead embodying my invention whosesurface is faceted.

Like reference characters indicate parts throughout the views.

In detail my novel bead comprises two hollow, substantiallyhemispherical sections or cups 10 of light material, in this instance ofcelluloid. rlhese are cut in circular blanks from a thin sheet ofcelluloid and cupped up by suitable dies, each blank being subjected toheat to render it temporarily pliable, to facilitate the bendingoperation. l.Vhen dry or cool the cups set in their acquiredhemispherical shape.

A substantially circular disk 12 is also like cut by suitable tools fromthe celluloid sheet or strip, and has a diameter substantially equal tothe maximum diameter of each of the cups. By suitable dies or otherwisethe disk 12 is impressed or channeled to form a diametrical groove 13.Thedisk is also provided with a peripheral cavity or slot 14; at eachend of the groove, extending inwardly a distance not less than thethickness of the walls of the cups 12. The cutting of the disk and slotsand the impression of the groove are by combined cutting and bendingdies performed simultaneously.

The three described pieces are now as? sembled as follows, the fiat edgefaces 15 of the sections 1() are fastened to the opposite faces of thedisk or wall 12 at the mar. gin of the latter so that the peripheries ofthe three members coincide toV form a continuous surface. The fasteningis effected by first applying a liquid celluloid cement to thecontacting portions of the members. Thisforms an adhesive lilm 18 whichwhen dry forms an invisible union of the parts. referring to Figures 1to 3 inclusive a suspension wire or co-rd 2O is shown upon which thebead is slidably mounted. The wires passes through slots 14C of the disk12 and within the depression 13 in the latter. ln Figure 7 the outersurfaces of the hemispherical sections of the cups 10 have facets 21.formed upon their peripheries which is desirable in case it is soughtYtov imitate a stone or gem. Y

The construction of bead shown in Figures 1 tol 3 inclusive isparticularlyadapted to use in such articles as necklaces. When the beadis intended for use as a pendant, as in ear ornaments, the modified formof beadl shown in Figure 5 ,is preferable. Herein the partition disk 22is employed, which omits the slots 14 and groove 13, but adds aperipheral shoulder 24 provided with a perforation 25 to receive asuspension loop or ring.

rlhe cups may be of any desired cross sec# tional contour, such as oval,and even rectangular. The partition plate may, if preferred, be annularin shape. In actual practice the partition plate is usually of differentcolor from the cups.

I claim:

1. An ornamental `bead comprising cups oppositely disposed with theircavities facing each other, and a disk disposed between the opposedfaces of the oups and cemented to the adjacent faces thereof, said beadhavin?,- provision for its suspension.v

2. rThe process of making a bead consisting in cutting` from a Celluloidsheet a circular partition blank, and two circular body blanks7subjecting the body blanks to heat to render the same pliable, bendingthe body blanks into cups, interposing the said partition blankdiametrically between adjacent faces of the body blanks with itsperiphery flush with that of the body blanks and cementing the cups toopposite lsides 0f the partition blank with the pe ipheries' of the cupsflush with the periphery of the disk.

Lacasse' 3. As an improved article of manufacture, an ornamental beaddesigned for jewelry and comprising two opposed substann tiallyhemispherical oups and a. substantially circular disk having a diametersubstantially equal to the maximum diameter of each of the cups, saiddisk being interposed between the flat edge faces of the cups with theperipheries' of the disk and cups coinciding to form with said cups acontinuousl surfaceT the adjacent faces of the disk and oups beingadhesively united, said bead havinp; means for its suspension.

ln testimony whereof have affixed nay signature.

HENRY F. JUERGENS.
